Granted: 1983-01-11
Abstract: Les indicateurs à cadran conventionnels, dont la précision est de l'ordre du millième de pouce et l'amplitude de l'ordre du demi-pouce, indiquent le déplacement linéarire absolu d'une tige faisant contacte en une seule de ses extrémités sur une surface, au moyen de deux cadrans circulaires gradués non-co-planaires situés d'un côté de l'instrument, tandis que l'autre côté sert de point d'attache de l'instrument. Le premier endran circulaire gradué dont la plus petite division est égale â la précision de l'instrument, est couplé à un longue aiguille actionnée par un arbre relié à un train d'engrenages. Ce premier cadran peut être mû et ajusté. Le second cadran couplé à une courte aiguille indique le déplacement cumulatif de la tige; la plus petite division de ce cadran représente cent fois la présision de l'instrument. La tige de contacte traverse le boîtier de l'instrument en deux points selon un diamètre. Ainsi la longueur de la tige de contacte et les dimensions du mécanisme d'attache de l'instrument sont des facteurs limitant son utilisation, notamment dans les espaces de dimensions voisines de le longueur de la tige. L'indicateur micrométrique double permet au lecteur d'observer des lectures identiques sur chacunes des deux faces principales de l'instrument. Le point d'attache est situé sur le côté du boîtier. Un tambour mobile ajustable (environ 80 degrés de rotation) à l'intérieur du boîtier, portant deux couronnes circulaires graduées, constitue une partie maîtresse de cet indicateur. Un petit cadran circulaire, indiquant le déplacement cumulatif de la tige apparait aussi sur chacune des faces. Tout ajustement effectué sur l'une des deux faces, est automatiquement et précisément reproduit sur la face opposée. En plus, l'instrument peut être calibré en permanence et ainsi servir de localisateur de surface lorsque fixé à l'arbre d'une machine-outil.

Abstract: ABSTRACT OF THE DISCLOSURE       EXPLORATION SYSTEM FOR ENHANCING THE LIKELIHOOD OF PREDICTING LITHOLOGY OF EARTH FORMATIONS ASSOCIATED WITH DEPOSITS OF ORE, MARKER ROCK AND/OR ECONOMIC MINERALS     The present invention provides for the accurate mapping of shallow crustal earth formations by means for refractive seismic waves to identify structure, elastic parameters and lithology of the strata undergoing survey to indicate deposits of ore, marker rock, economic minerals and the like.  After a "roll-along" technique has been used in the field to collect the refraction data and preliminary processing steps undertaken in which there are provisions for (i) accurate separation and determination of seismic shear and compressional responses; (ii) stacking displays that allow for accurate identification of shape of the surveyed strata; and (iii) final depth displays of the refracting bed segments associated with seismic shear and compressional wave velocities as well as Poisson's ratios, in accordance with the present invention, additional processing then occurs.  The added processing indicates lithology of the earth formation to a surprising degree based, inter alia, on multi-dimensional space searching techniques.

Granted: 1982-08-17
Abstract: ABSTRACT OF THE DISCLOSURE     A double-safety emergency locking belt retractor for vehicle safety belt systems comprises an improved automatic-locking mechanism in which an axially movable latch disc locks the reel to the retractor frame upon rotation of the reel relative to an inertia wheel in the belt-unwinding direction.  Such relative motion occurs when an inertia-sensitive device stops rotation of the inertia wheel in response to acceleration of the vehicle at from about 0.3g to about 0.7g or the inertia of the wheel causes it to lag the reel when the belt is accelerated at about 0.7g or higher.  The latch and inertia wheel are cammed axially apart upon such relative rotation, the inertia wheel being locked to a cover for certainty of cam function and the latch disc thereupon being locked to the frame.

Abstract: ABSTRACT A method for recording track marking information on flexible mag-netical information carrier discs, in which the circular tracks on one side of the disc are each divided into an information recording segment having an angular width of at least 270° and a remaining track marking segment, and in this latter respective marking frequency signals are recorded so that each of these signals is distinguishable from those recorded on the two neighbouring tracks.  The invention relates to an apparatus for fine adjustment of the position of a reading head in case of discs recorded by the above method.  The apparatus comprises frequency selective means that selects the marking fre-quency components when track marking segments are played back.  The difference of the sensed components are processed to a control signal which drives a control unit for adjusting the radial position of the head to the center line of a predetermined track.  The invention is sensitive against eccentricities of the track and it ensures almost a double storage capacity compared to conventional floppy discs, or it uses simple playback systems in which double head movement is not required.
